When offering FedEx, rates are determined by weight, with a minimum weight of 0.1 pounds. If the weight is less than the minimum, then the shipping charge is calculated using the minimum weight.
NOTE: If you select to ship multiple products in the same package, you must configure the maximum weight and size you can use. Items are packed automatically based on declared item volume and declared box volume. Items exceeding max box weight or size ship separately. For more information about 'Dimensional Weight,' see the FedEx Dimensional Weight document.
